Hi 何胜利，

Please kindly refer to the following answer for your question:

1，what is D-FLAS 0 IFR abs address ?  CAN I read it from IAR debug?

-D-FLAS 0 IFR can only be accessed by Read Resource Command, please refer to the following for details.

2，How many bytes about 1 Flash Block,1  Flash Section,where to set it?

-Do you mean flash section instead of flash section? Actually the size of flash block and sector are determined by device, no register can be used to configure them on the fly. Please kindly refer to Chapter 3 Chip Configuration in RM for details. You may find something like below:

3,when I earse one  Flash Section ,how many byte I earsed ? earsing  start address is setted by FTFE_FCCOB1,FTFE_FCCOB2,FTFE_FCCOB3?

-Do you mean erasing Flash sector command? Then the bytes to be erased is size of a sector, for example, 4KB. and yes, earsing  start address is setted by FTFE_FCCOB1,FTFE_FCCOB2,FTFE_FCCOB3. Please refer to the following for more details.

Hope that helps,

Have a great day,
Kan
